Smell and Taste Games: Engaging the Olfactory Sense to Reduce Food Neophobia

When it comes to expanding a child’s culinary horizons, the sense of smell often takes a back seat to sight and texture. Yet the olfactory system is a powerful gateway to flavor perception, memory, and emotional response. By turning scent and taste into playful, low‑pressure experiences, parents and caregivers can gently dismantle food neophobia—the fear of trying new foods—without resorting to force or confrontation. Below is a comprehensive guide to designing, implementing, and scaling “smell and taste games” that tap into the brain’s natural curiosity and reward pathways.

Why Smell Matters More Than You Think

The Science of Flavor Integration

Flavor is a multisensory construct, but roughly 80 % of what we perceive as taste actually originates from olfactory cues. When we chew, volatile compounds travel from the mouth to the nasal cavity (retronasal olfaction), merging with gustatory signals from the tongue. This integration occurs in the orbitofrontal cortex, a region linked to reward and decision‑making. By stimulating the olfactory system first, we prime the brain to anticipate a pleasant taste, making the actual eating experience less intimidating.

Memory, Emotion, and the Limbic System

The olfactory bulb has direct connections to the amygdala and hippocampus, structures responsible for emotion and memory. A familiar or pleasant scent can evoke positive feelings, reducing anxiety associated with unfamiliar foods. Conversely, a neutral or mildly intriguing aroma can spark curiosity without overwhelming the child.

Developmental Timing

Infants can detect odors in utero, and newborns show preferences for certain smells (e.g., vanilla, sweet). By the time children reach preschool age, their olfactory discrimination is well‑developed, making it an ideal window for targeted sensory play.

Core Principles for Designing Smell‑Based Games

1. Low Stakes, High Fun – The activity should feel like a game, not a test. Emphasize exploration over correctness.
2. Gradual Intensity – Start with mild, universally pleasant aromas and slowly introduce more complex or unfamiliar scents.
3. Multimodal Pairing – Pair a scent with a matching or complementary taste to reinforce the connection (e.g., citrus aroma with a tiny sip of orange juice).
4. Choice and Autonomy – Offer multiple scent options and let the child decide which to explore first. Autonomy reduces resistance.
5. Repetition with Variation – Revisit the same scent in different contexts (e.g., as a “mystery smell” or as part of a “flavor treasure hunt”) to strengthen neural pathways.

Game 1: “Scent Detective”

Objective: Identify hidden aromas and match them to corresponding flavor clues.

Materials:

• Small, airtight containers (e.g., mini glass jars with lids)
• Cotton balls or scent‑infused pads
• A set of “flavor cards” featuring simple taste descriptors (sweet, sour, salty, bitter, umami) and associated foods
• Blindfold or a “mystery mask”

Setup & Play:

1. Prepare 6–8 containers, each holding a distinct scent (e.g., vanilla bean, fresh basil, grated ginger, toasted almond, lemon zest, cinnamon).
2. Place a flavor card next to each container, but keep the card face down.
3. The child, wearing the blindfold, selects a container, inhales, and guesses the associated taste descriptor.
4. Reveal the flavor card; if the guess is correct, award a “detective badge” (a sticker or token).
5. After a few rounds, introduce a “wild card” scent that is a blend (e.g., orange‑cinnamon) and encourage the child to identify both components.

Why It Works:

• The blindfold removes visual bias, forcing reliance on olfaction.
• Matching scent to taste reinforces the brain’s flavor integration pathways.
• The badge system provides positive reinforcement without pressure to eat.

Game 2: “Flavor Memory Match”

Objective: Strengthen the link between a scent and its corresponding taste through a memory‑style card game.

Materials:

• Two decks of cards: one with scent images (or printed scent names) and one with taste images (e.g., a picture of a strawberry for sweet, a lemon for sour).
• Small scent jars or scented stickers that can be attached to the scent cards.

Setup & Play:

1. Attach a scent pad to each scent card.
2. Shuffle both decks and lay them face down in a grid.
3. The child flips two cards at a time, sniffing any scent card revealed.
4. If the scent matches the taste card (e.g., “mint” scent with “cool” taste), the pair is removed, and the child earns a point.
5. Continue until all pairs are matched.

Why It Works:

• The memory component engages the hippocampus, reinforcing the scent‑taste association.
• Repeated exposure to the same scent in a low‑stakes context builds familiarity, reducing neophobia.

Game 3: “Taste‑Scent Relay”

Objective: Create a dynamic, movement‑based activity that pairs a scent with a quick taste test.

Materials:

• A set of scent stations (small trays with scented cotton balls) placed around a room.
• Corresponding bite‑size taste samples (e.g., a tiny piece of apple for “apple” scent, a pea for “sweet pea” scent).
• A timer or musical cue.

Setup & Play:

1. Arrange the stations in a circle.
2. When the music starts, the child runs to a station, sniffs the scent, and then quickly tastes the associated sample.
3. After the taste, they return to the start line before the music stops.
4. If the child correctly identifies the scent‑taste pair, they receive a “relay token.”

Why It Works:

• The kinetic element adds excitement, making the sensory experience memorable.
• Rapid pairing reinforces the brain’s ability to link olfactory and gustatory cues under mild time pressure, which can translate to quicker acceptance of new foods.

Game 4: “Scent‑Storytelling”

Objective: Use imagination to embed scents within a narrative, encouraging emotional connection.

Materials:

• A “story jar” containing a neutral scent (e.g., warm water) that can be swapped out.
• A set of scent cards (similar to Game 1).
• A simple story template (e.g., “Once upon a time, a brave explorer discovered a mysterious…”)

Setup & Play:

1. Choose a scent card together.
2. The child (or adult) weaves a short story that incorporates the chosen scent as a key element (e.g., “The explorer entered a forest where the air smelled like fresh pine”).
3. While narrating, the child inhales the scent from the jar.
4. After the story, discuss how the scent made them feel and whether they’d like to try a food that shares that aroma.

Why It Works:

• Narrative framing taps into the brain’s language and emotional networks, making the scent more memorable.
• Positive emotional associations can lower the affective barrier to trying related foods.

Game 5: “Blind Aroma Tasting” (Advanced)

Objective: For older children (7+), deepen the sensory challenge by combining blindfolded tasting with scent identification.

Materials:

• A set of opaque cups with small openings for smelling.
• A selection of flavored extracts (e.g., vanilla, almond, citrus, herb) diluted in water.
• A tasting spoon with a neutral base (e.g., plain yogurt).

Setup & Play:

1. Place a few drops of an extract into a cup, cover it, and label it with a number.
2. The child, blindfolded, sniffs the cup, then takes a tiny spoonful of the base yogurt.
3. They guess the flavor and note whether the taste matches the scent.
4. Reveal the correct answer and discuss any surprises.

Why It Works:

• This game emphasizes the retronasal pathway, reinforcing the link between smell and taste.
• The neutral base prevents strong taste bias, allowing the scent to guide perception.

Practical Tips for Success

Integrating Smell Games into Daily Routines

1. Morning Routine: While preparing breakfast, let the child sniff a fresh herb or fruit slice before eating.
2. Snack Time: Offer a “scent of the day” card alongside a small snack, encouraging a quick sniff before the bite.
3. Bedtime Wind‑Down: Use calming scents (lavender, chamomile) paired with a warm drink to create a soothing association with flavor.
4. Grocery Trips: Turn the produce aisle into a “scent hunt,” asking the child to identify the smell of different fruits and vegetables before selecting them.

Measuring Progress

• Scent Familiarity Log: Record which scents the child can identify confidently over time.
• Taste Acceptance Scale: Note any new foods the child tries after a related scent game (e.g., after “cinnamon” scent, the child tries a cinnamon‑spiced oatmeal).
• Emotional Response Chart: Use simple emojis to capture the child’s feelings before and after each game (e.g., 😐 → 😊).

Tracking these metrics helps parents see tangible improvements and adjust game difficulty accordingly.

Frequently Asked Questions

Q: How often should we run these games?

A: Consistency beats intensity. Two to three short sessions per week are sufficient to build familiarity without causing fatigue.

Q: Are essential oils safe for children?

A: Only use food‑grade, therapeutic‑grade oils, and dilute them to a concentration of 0.5–1 % (approximately one drop per teaspoon of carrier oil or water). Avoid citrus oils on sensitive skin and always check for allergies.

Q: What if my child dislikes a particular scent?

A: Respect the reaction and move on. Neophobia often stems from negative experiences; forcing exposure can backfire. Re‑introduce the scent later in a different context.

Q: Can these games help with picky eaters who have sensory processing issues?

A: Yes. By providing controlled, predictable olfactory exposure, the games can gradually desensitize the child and reduce sensory overload.

Closing Thoughts

Harnessing the power of smell transforms the act of eating from a purely nutritional task into an adventure of discovery. By embedding scents within playful, low‑pressure games, caregivers can gently rewrite a child’s internal narrative around food—shifting from “I’m scared of new flavors” to “I’m curious about what’s around me.” The key lies in consistency, positivity, and respecting the child’s pace. With these smell and taste games in the toolbox, the journey from hesitant nibble to enthusiastic palate explorer becomes not just possible, but enjoyable.
